RESILIENT WHEEL.

Application filed February 11, 1922.V Serial No. 535,871.

and one of the objects is to produce a wheel o element shall be pro-l.vided for holding the side walls of the tirev in which a spacing memberapart and in which bead gripping plates when drawn together willco-operate with the spacing element so as the sides of the vtire elementto be ened and Vdrawn taut. Y e

Another object is to produce a spacing element which shall be simple ofconstruction and efficient in operation.

Another object is to provide novel and improved gripping andsecuring'means.

Another object is to produce a device of this nature in which the tiresupporting rim and spring shall be so constructed and positioned thatthe shocks received by the wheel shall not be received in the length ofthe grain of the steel, and the entire shock shall not be sustained bythe spring, whereby crystalization of these parts will be prevented.

Another object is to produce a device of this nature in which the solepurpose of the spring or resilient device shall be to restore thesupporting rim to normal condition.

Another object is to produce a device of this nature which shall besimple of construction, inexpensive to manufacture, and highly efhcientfor the purpose for which it is designed. Y f

` With these and other objects in view which will be apparent as thespecification proceeds, construction and combination and arrangement ofparts, theV essential features of which are hereinafter fully described,are particularly pointed out in the appended claims and are illustratedin the accompanying drawing, in which z- Figure 1, is a side elevationof my improved resilient wheel, parts being broken away for the sake ofclearness.

Figure 3, is a detail plan view of a portion of the tire supporting rim.

Figure 4, is a vertical sectional view of the same. f t

Figure 5, isa sectional perspective view of a modified form of rim.

Like characters of reference refer to like parts in the several views.

Referring to the drawingin detail, it will be seen that there is asleeve 10 which is meant to be rotatably mounted on the aXle of thevehicleand the outer end of 'which is provided with a flange 11 carryinga block or seat 12 of any suitable material. An inner plate 13 is boltedto the flange 11 and block 12 as at 14. A cap member 15 embraces thelcentral portion of the outer plate 16. The plates 13 and 16 are securedtogether by bolts or other suitable means as at 17.

rl`he outer portion of plate 16 is formed into a bead receivingannulargroove 18 adapted to receive the bead 19 of the tire. The periphery ofplate 13 is bent laterally to form a ange 20 which is provided at itsextremitywith a vertically disposed portion 21 formed into a beadreceiving element for receiving the bead 22 of the tire portion. Betweenthe members 13 and 16 and slidable on the element 2O is a plate 23, thepurpose of which is to receive certain lugs of the bead 19 te preventcreeping of the tire. The flange 20 and member 23 are provided withdepressions 24 at intervals into which lugs 25 of the beads 19 and 22respectively are adapted to lit, the co action of such lugs anddepressions preventing any possibility of the tire creeping. The sides26 of the tire are spaced apart by an annularmember 27 provided with aplurality of legs 28 whichare seated on the elements 20 and 23. The legs28 are formed with cut-out portions 28a to reduce the weight-of said'ring. The outer part of the tire `may be provided with the usual rubbertread 29 of any suitable style. At the outer portion of the tire 26,there is provided a ring comprising a plurality of blocks 30having ears31 formed at the ends of side flanges 32, said ears being pierced andpivotally connected by pivot bolts or pins 33, The ends of the bodyportions of blocks 30 are bent into flanges 34, which are curved so asto fit about the pivot pins 33 and these flanges 34 limit the amount ofmovement permitted to each pair of blocks 30. A channel iron 35 issecured to the interior of eachV block forming strengthening ribs.Inside of the rim coniposed of the members 30 there is provided,V

the sides of the tire elements will be drawn.

taut as the annular membervQTprevents any inward movement ofthe sides,and theV beads in Vbeing forced under sai'dmember 27 ,draw the sides 26ofthe tire straight and tight,v thereby drawing the tire and annularmember ment,

The members 30 and-35 are perforated at A and Bfrespectively so thatVwhen these members are moulded in the rubber tread of the tire, therubber willflow V.into these perforations to firmly Asecure thesemembers in position. Y ,i

Inthe modified form shown in Figure 5, the blocks 30a, are formed withone pointed end 30", and a V-shaped notch 30", inthe other end.v Theseblocks are provided with ears 3la which are the sameas ears 31 in thefirst embodiment of the invention. These ears `may be pivotallyconnected together by bolts 32a. When placed end to end, they permit of-a considerable amo-unt of .resilience and at the same time form acompact and strong supporting` means.

While I have herein fully shown and described and have pointed out inthe appended claims certain novel features of construction, arrangementand operation which characterize my invention, it will be understood bythose skilled in the artl that various omissions,.substitutions andchanges in the forms, proportions, sizes, of the materials used,^and oftheir operation, may be made without depart-ing from thespiritof myinvention. i'

What I claim as knew is 1. A resilient wheel comprising a pair ofplates, the peripheryl lof each of which is formed into a bead grippingmember, means securing said lplates, together,` means supported by saidplates for holding the walls of a tire in expanded condition, a tireinto complete and intimate `engage-V cluding beads for co-operation withsaid formed-fromapliirality of substantiallyV identical blocks, eachblock formed with side and end flanges and a'tire'body in which saidring is embedded.
